Dar-Tech Hauthane L-3645 is a NMP- and TEA-free, aliphatic, silicone-modified, polyester-based, waterborne polyurethane dispersion. It was designed primarily for topcoat applications where slip resistance and abrasion resistance are required. L-3645 contains a non-fugitive silicone component that provides low surface tension characteristics on flexible and rigid substrates, including leather, plastics, metals, and textiles. It also demonstrates exceptional dye transfer resistance in automotive leather seating and dry-erase white board applications when crosslinked.
